I keep getting the error on my apply model part of the process. How do I make the attributes match?

    Hi,

     

    you need to do the same transformation the right hand side than on the left hand side. So the nominal to numerical needs to be before the apply model ensure that you also get them over.

     

    Better: Use a group models. Otherwise you can still run into problems that some classes are not there.
